Does Weed Go Bad? Here’s How Long Weed Lasts

If it’s stored improperly it may either become too dry (and lose its potency and taste) or it may go moldy (which makes it toxic to your respiratory system due to mold spores).

How should cannabis be dried and stored?

In some respect, cannabis is similar to dried kitchen herbs such as parsley, basil, oregano and such. Once the flowers are harvested, they are first dried — this is done by keeping the buds in a dark, room temperature place.

After that, the buds should be placed in an air-sealed jar where they go through a process called curing. The moisture content inside the buds is reduced to 62% and curing allows the buds to break down sugars and achieve maximum flavor and potency.
